You cannot unlock (or "reset") a locked unit without the PIN number or going to the location where the PIN was set. The only other option you have is to send the unit to Garmin.

Sounds very much like the wiring plug connections in the back, always overlooked but so important that connections are tight and contacting.

I have the same problem. Did you ever figure out why it was not loading? There are no software adjustments to be made. Just plug in the card and wait. It says its reading the card, but never goes any further. Let it 'read the card' for hours with no luck. Help!!!
